Be it known that l, Louis Koornnsrnnv, a citizen ot' the Unitec States, residing at New York, county and State of New York, have invented certainnew and useful lmprovements in Dispensing Valves, ot which the following is a full, clear, and exact description. Y

This* invention relates more particularly to that class ot valves operated by a pushrod or plunger to dispense aliquid such as soap, the liquid passing into the valve from a source of supply. The object of the'presY ent invention is to provide an effective and simple device of the type in question avoiding the use et' paolrings or washers, other features of the invention being hereinafter referred to. 'v

F or an undei-standingolf the invention reference may be made to the accompanying Figure l illustrates an embodiment oit the invention inenlarged longitudinal cross section; and

Figure 2 is a transverse section on the line 2-2 ot Figure 1, in the direction of the arrow. o

lThe embodimentof the invention illustrated in the drawing comprises a'casingl formed at its upper end with an inwardly projecting annular Hang-e 1X, which is threaded to receive the threaded upper end of a sleeve member 2, the lat-ter being formed at its lower end with a conical extension 3 and an annular flange 11, the tlange being provided with seats 5 for the reception ot' a toolr adapted kto rotate the sleeve within the casing during the assembling ot the parts. The ange 4- its within an annular recess 6 formed in the lower end of the casing to Vprovide a shoulder 7, a packing 8 being disposed intermediate the said shoulder and the flange il. Threaded upon the upper end ot sleeve 2 is a cap 9 provided with a conical aperture 1() through which iiuidvmay pass into the sleeveq when this is permitted by the position ot a ball 11 normally resting against the conical upper walls of an aperture l2, formed in a disk 13 threaded within the cap. It will be seen that fluid may pass into the sleeve only when the ball is in a position intermediate the valve seats afforded by the conical apertures 10 and 12.

The immediate actuating member for ball 1l is a rod le, the rod in turn being oper- 'the rod.

Theplun ger is normally maintained in its lowermost positionas illustrated in Figure l by means ot a helical spring 18, the-spring at one end acting against a rshoulder 1Q formed on the plunger7 and its ropposite end 'contacting with the lower tace or disk 13.

By means ot the annular flange l et the casing, sleeve held in such position as to retreated nay ie, ieee,

`provide auchamber 20intermediate its outer wall and the inner wall ot the casing. This chamber communicates with the interior ot e the sleeve through an inlet duct 21 and an outlet duct 22. l n

ln the operation el the device` upward movement et' the plunger 5 l will, throughspring 16, carry the upper end ot rod 111- into contact with ball 11, the latter vbeing unseated from disk 13 and thence beingm'oved against the conical aperture 110 in the cap so as to again close the sleeve against the admission of fluid. lt will be noted that i as the ball reaches a position intermediate the apertures 10 and 12 fluid may flow into the sleeve. stationary, the plunger may have a con-` tinued movement because of the provision oi a clearance intermediate its lower end to the ybase of soolzet 15X; and in its continued movenient the conical or reduced portion of the plunger passes above outlet port 22 and fluid contained within chamber 20 may pass intermediate the sleeve and the plunger, the latter being cut away at 23 for this purpose. At the instant outlet duct 22 is opened the plunger moves in position to close inlet port 21. It desired, however, inletI port 21. may be disposed above the range ot movement vof the plunger and henceliquid may llowinto chamber 20 during the discharge through port 22. Upon the release of the plunger valve rod 14C moves downwardly and ball 14; in its movement toward seat 12 again reaches Although the rod now remains yel() sleeve to replenish that discharge through' port Q2, and in the continued movement of the plunger' inlet duct 21 is opened and outlet duct 22 is closed.

It will be noted that inasmuch as disk 13 is threaded within cap 14, the length of movement oi ball 11 to and from its intermediate position, may be adjusted. For the convenient manipulation of disk 13 it is 'formed 'with a transverse slot 13X to receive a screw driver or other tool.

Having described my improvements, what l claim is:

l. In a dispensing` valve, in combination, a casing, a sleeve disposed within said casing to form a chamber intermediate its outer wall and the casing, inlet and outlet ducts for said chamber and communicating with the interior of the sleeve, a valve controlling the admission of fluid into the sleeve, a plunger normally closing the said outlet duct, the said plunger being adapted in its end'wise movement to operate said valve and to successivelyv close the inlet duct and open the outlet duct for the passage of fluid from the chamber, thence intermediate the sleeve and the plunger to a point exterior to the casing.

2. In a dispensing valve, in combination, a casing, a sleeve disposed in said casing to form a chamber intermediate its outer Wall and the casing, inlet and outlet ducts for the chamber and communicating with the interior of the sleeve, a valve normally closing the sleeve against the admission oi fluid, a plunger movable within the sleeve and ormed With a passageway for iuid, avalve operating rod, a spring flexibly connectingthe rod and plunger, a second spring nor-- mally maintaining the plunger in position to close the outlet duct, whereby an endwise operative movement o1" the plunger will successively close the valve, close the inlet duct and bring the outlet duct into communication with said passageway.

3. ln a dispensing valve, a casing adapted to contain liquid formed with an outlet port, plunger movable to open and close the outlet port, an inlet valve for the casing comprising a cap formed with a central aperture and a threaded interior wall, a ball adapted to be moved in position to c'lose the aperture and a disk threaded for adjustment within the cap, the said disk being formed with an aperture aording a seat for the ball, and means carried by the plunger for unseating the ball.

4. ln a dispensing valve, in combination,

a casing, a sleeve disposed within the casing to provide a. chamber intermediate its outer Wall and the wall of the casing, inlet and outlet ducts for said chamber and communicating with the interior of the sleeve, a plunger disposed within the sleeve, a double-acting valve controlling the admission of fluid to the sleeve, a valve-operating rod, a spring yieldingly connecting the rod and plunger, a second spring acting'to normally maintain the plunger in position to close said outlet duct, an operative movement or the plunger actuating the rod to successively yclose said valve and open the outlet port, a return movement or' the plunger actuating the valve to successively permit and shut off flow ot fluid into the casing 'and the plunger in its continued movement closing the outlet port. i
